General Overclocking Notes: 1.7Ghz is likely as far as we can push the Tegra2 cores. We have stress tested the heck out of 1.7 and it is safe. However, safe does not mean stable. Personally, I can run 1.7 on Interactive governor all day and it's smooth as butter. Other folks get reboots. If you can not run at 1.7, try 1.6. Everybody who tested was able to run at 1.504 without any problems. Just because this release is clocked to 1.7, that does not mean you can not run at stock speeds. Simply do not overclock. The settings for 1Ghz are identical to stock settings. I HIGHLY RECOMMEND you leave your device on INTERACTIVE. You may use Performance solely for benchmarking purposes, but then PUT IT BACK.​

Release Notes:

Version 2.2.0

Woah... it's been a while since the last kernel release!

For this release, I have to give a huge shoutout to kcrudup, who was able to obtain the new modem drivers that are required for 4G to function.

Other than the 4G support, we have also added support for the lagfree cpu frequency governor.

Your first boot may take a while, depending on how many applications you have installed. Mine took about 8 minutes.

--solarnz
​

Version 2.1.0

So here it is! The first kernel since the merge of Tiamat and Launchpad!

Firstly, thanks to TDR the wifi sleep issue is now fixed!

We have also fixed the under/overvoltage settings for 1.7 Ghz.

Missing from this release is Usb Mass Storage support. (Not usbOTG, where the Xoom is the usb host) In 3.2 we are able to access the external sdcard through the MTP protocol and removing support for this helps the stability of the usb connectivity on the xoom.

(USB Mass storage support is buggy)

We have also brought in a LOT of changes from nvidia with regards to bug patches and enhancements for the tegra platform.

Due to some of the changes by nvidia, when your device boots, after it displays the motorola logo it will show distortion before the boot animation. This is normal on this kernel and doesn't seem to effect the device at all.

You would of also noticed that we've moved to another thread from this release. This is to help differentiate between the 1.x.x series which is not supported on Android 3.2, and likewise with the 2.x.x on 3.1.

Any info regarding this new kernel? Maybe some....
[Xoom Android Development] Alistair25:
Nice to see another kiwi on the forums, have just ordered my Xoom from Amazon, due to arrive (and subsequently run Tiamat!) next week. Gotta love that USD rate at the moment!
[Xoom Android Development] penjejakawan:
why "Removed the usb mass storage support. (being able to write directly to the external sdcard via your pc)", is there any problem arise from this?

EDIT : Sorry, didn't read your post. So excited actually. I also experienced reboot when connected to pc thru usb but i thought it's not the problem..hehhee.

EDIT 2: i don't know what wrong from CWM 3.2 after choose mount usb storage, i cannot see my external micro sd from my pc. I tried 2 times into recovery but still failed to detect my external sd card. If someone know the solution, please share with me. Because if i cannot find the solution, i cannot upgrade to this new kernel. Why? Because if i want to use my external sdcard, i will have to disable my 3g card just to remove the external sd card and connect it to my pc using micro sd card read.
[Xoom Android Development] keunhuvac:
WOW! It comes too soon :D :D
[Xoom Android Development] stigmax:
win....installing now
[Xoom Android Development] davidsos:
The upgrade from the last gpu oc kernel went without incident. I did get a system lockup when viewing a video on cnet.com in dolphin hd and maximizing it while it was playing. The screen froze and there was a buzzing sound coming from the speakers. I forced a reboot, two button salute, but was not able to reproduce it while watching the same video.

So far it's nice and responsive. Boy do we get frequent updates with far better results than from Motorola/google.
[Xoom Android Development] swcowger:
Downloading now you guys rock.
[Xoom Android Development] Sardo Numspa:
thanks guys

edit: flashed and running smooth so far.
[Xoom Android Development] wsuo2006:
difference?

Can someone tell me the difference of these two packages?

One is from https://github.com/Tiamat-AOSP/Tiamat-Xoom, the package is

Tiamat-AOSP-Tiamat-Xoom-Tiamat_2.1.0-0-g5b6121e.zip

Its size is 103 mb.

The other one is the kernel downloaded from here.

Does the first one include rom?

Thanks
[Xoom Android Development] wsuo2006:
google map still can't be updated, and browser still crashes for "find on page"
[Xoom Android Development] joshndroid:
Flashed and works great will this be coupled with a rom update?
[Xoom Android Development] Bazar617:
Very nice, will flash soon.
[Xoom Android Development] edgardcastro:
Working perfectly on the 3.2 Non-US 3G ROM.

Many Thanks Team Tiamat!

This is truly awesome...so smooth and with the OC gpu, games are working like a dream.

That's not the same thing. That's just to root your your Xoom. The Tachi kernel is to overclock. I saw that there are some who stated they used it with no issue yet others saying it messed up their connection.
[Xoom Android Development] hammer4203:
Yeah thats y I ain't done it yet. Maybe there is a step thats overwriting something that it shouldn't.
[Xoom Android Development] Isun:
I tested it and it works fine with the 4G LTE upgraded Xoom.
[Xoom Android Development] electronics18:
I thought it worked fine at first too, but the next day the data, both Wifi and 3G/4G would stop working and the only way to get it back was to restart the device, where it would only work for about 15 minutes before going out again. I performed a nandroid backup before I installed the kernel so I restored my nandroid backup and now everything SEEMS to be fine again, I just don't have OC anymore.

I received my Xoom back wiped and updated, I immediately took it and unlocked it, then rooted it and performed a nandroid backup. I then restored my apps with titanium backup and then installed the kernel. Everything seemed fine at first but after going to bed the next morning I woke up to find no data (this was Wifi). I took it with me to work on 3G and it would cutout every 15 minutes or so. I restored the backup then did another titanium backup restore and it has been fine since.

Did you do anything different to yours if it is still working correctly with the kernel?
[Xoom Android Development] Isun:
I didn't keep it in over-night because I was testing a few other things out with my nandroid back up. I just got done doing a wipe and reset to fix a market issue. If all goes well I will flash the Tachi kernel again and keep it on overnight to see what happens. I had it on for about 3hrs with no issue.
[Xoom Android Development] LsRamAir:
Finally someone with my identical situation and problem! I restored the kernel from moto and no more wireless death sleep.
[Xoom Android Development] electronics18:
Let us know, I had no problems at first either because I was using it constantly after the flash, it seems to be an issue with when it goes to sleep not when it is being actively used. For now it looks like we are going to have to do without OC on any 4G upgrades until an updated kernel is released.
[Xoom Android Development] Isun:
Tachi kernel works with upgraded 4G Xoom

I have been using the Tachi kernel since yesterday on the 4G Xoom and it works perfectly fine. I have tested it every way possible by keeping 4G on switching to 3G then to WiFi then back quite a few times. When I woke up the screen was off and I turned on tested all connections again and it worked perfectly. I rebooted after an hour and spent some time surfing and streaming with each different type of connection. All is well and my max speeds are around 7MBs upload and 12MBs down though it seems to be around 5-8 most of the time. I will test speeds in another area. Running at 1.5Ghz.
[Xoom Android Development] okantomi:
Fantastic news for our 4G friends. Did you do something special to make sure it installed cleanly, etc?
[Xoom Android Development] avetny:
I like kernel !

Smooth, fast, nice benchmarking scores !;)
[Xoom Android Development] gordy_2001:
vpn

will this kernel support the any connect vpn app? or is that not relevant to the o/c part of this kernel??
[Xoom Android Development] Isun:
The only thing I did was do a wipe/reset because when my upgraded Xoom came back it had market issues, root using Universal Root method, reinstall my apps then applied the Tachi kernel. It has been working fine.
[Xoom Android Development] despich:
Tachi seems OK for 4G Xoom after all

I went ahead and got gutsy and put on the Tachi "[KERNEL][AOSP]Tiamat Xoom 2.1.0 "Tachi" [Update: 08/03]" kernel in hopes it wouldn't screw up the 4G yesterday and I could get OC back. So far it's been fine for me. I have brought it out of sleep about 15 times and so far it hasn't had any glitches.

I did notice that this morning I was already out of battery which surprised me a little but that may be just a fluke. I was using it a ton yesterday afternoon. If I have any issues I will be sure and come back and post them here. I was on the 75D before with the stock 4G kernel (one from the upgrade place). Tachi is the only kernel I have tried.

on a side note: For me at my house the 4G signal is actually stronger than my 3G, i can get 4g pretty reliably and fast from my basement and I can't get 3G at all from down there.
[Xoom Android Development] PengLord:
I ran this kernel prior to the Tiamat ROMs coming out, now that I've upgraded to 4G, I'm running it again, the only problems I've encountered are that I can't seem to write to the SDcard (mnt\external1) unless using Root Explorer (in the past I could use EStrong) and I cannot see USB drives using my USBOTG cable (worked prior to the upgrade). It's entirely possibly I missed some step someplace, though I reviewed the installation steps several times to be certain. If you're using this kernel with a 4G Xoom running 3.2.2, can you tell me if you're having these issues as well?
[Xoom Android Development] Isun:
4G is the cause of the extra battery drain. What type of speeds are you getting?

---------- Post added at 11:23 AM ---------- Previous post was at 11:20 AM ----------

There must be something with the 3.2.2 HLK75D update that causes it but all I did was allow root access to File Manager HD and that took care of it.
[Xoom Android Development] PengLord:
Interesting... I installed File Manager HD, enabled Root Explorer (in the settings menu) and it prompted for Root permissions. It works great. The next step in resolving this is going to be remounting the external1 device on boot to enable global write support. As I'm not so well versed in Android architecture to do that, I'll use MicroSD Mounter manually on boot.

The final step to getting this all sorted will be for me to figure out how to mount usbOTG devices, If anybody has experience with that on this kernel with a 4G Xoom, I'd very much appreciate it.

I figured out my problem with usbOTG support... I needed to added the "usbOTG" folder in the "mnt" directory using Root Explorer and then install a mount manager such as USB Mass Storage Watcher OTG
[Xoom Android Development] despich:
Note sure its a problem, but 2 times, i have not been able to wake up the xoom at all. I know it's on because trying to turn it on does't do anything. but all i get is a black screen, i end up having to do the reset (Vol up and Power) to reset it. It's only happened twice out of about 30 wake ups over 2 days.

My battery also seems to be worse. I know 4G should make it worse but 3/4 of the time it should have been on WI/FI so it's hard to believe it made that much difference. That is just a hunch i haven't done any accurate testing.

---------- Post added at 09:07 AM ---------- Previous post was at 08:47 AM ----------
[Xoom Android Development] despich:
I spoke too soon. I just had the no wireless at all problem on wake after putting tachi on my 4g xoom. I had to reboot in order to get anything to work. Dang it.... I hope someone came out with a 4g compatible kernel soon. I will live with this one for a few days in hopes they do ..
[Xoom Android Development] Isun:
Mine is still running fine with the kernel but my friend just informed me that he too ran into the connection issue after using with no problems for two days.
[Xoom Android Development] LsRamAir:
When the wireless death sleep issue occurs randomly while on this kernel... the reception will show red in the battery usage and battery will die completely in about 5 hrs. I cant wait for a new version to release, as missing the extra CPU performance is a major drag when u have been used to it for so long.
[Xoom Android Development] Saintfyre:
Been having issues with the sleep/no wake also.

Have to do a hard reset (Volume Up + Power) to get it going again.

Usually occurs if I let it sleep w/ Wifi enabled for more than 30 minutes... also if I don't have wifi enabled when it goes to sleep,

if

it wakes up there's no mobile network connection..
[Xoom Android Development] SickZX6R:
I have only been running 1.4.1 for a little while, but it seems to be running OK. I get super low Quadrant scores (2200 at 1.7GHz on Performance, what gives?) though.

I too just got mine back from Motorola this morning. I am getting 23.11Mbps down and 11.68Mbps up on LTE. Battery life seems to be substantially worse.
[Xoom Android Development] despich:
Putting the current Tachi Kernel on a 4G upgraded Xoom will cause problems with your networks on wake or problems waking in general. It will also Cause bad battery performance. Did you put Tachi on your 4G xoom?
[Xoom Android Development] Isun:
The bad battery thing is just due to using 4G in general but yes I too can now confirm as of this morning that the Tachi kernel will eventually cause a wake/connection issue. I ran it for almost a week with no issue but as with everyone else the connect issue arose. Well, we can wait for an ICS ROM :) or a new OC kernel.
[Xoom Android Development] despich:
When I went back to the stock kernal (flashed the boot.img and system.img AxeMachine 75C version and then went to 75D) my battery is much much better. Pretty much the same as it was before the 4g upgrade.
[Xoom Android Development] davidsos:
Hold your Xoom in portrait orientation when running quadrant. Do that and you'll get the right scores.
[Xoom Android Development] Saintfyre:
This is a bit off topic, but I just flashed AceXMachines HLK75C boot and system images to get back to the stock kernel after Tachi was giving me an aneurysm. How did you get back to HLK75D, I'm not getting an OTA update, and my System Updates in settings says it's up to date.
[Xoom Android Development] LsRamAir:
Somone posted it as a download, flash it in CWM and you will be back on D. Thats what i did.
[Xoom Android Development] ghoticov:
Is anyone running this kernel on 3.2.2 with success (just the kernel, not a ROM)?
[Xoom Android Development] kin24173493:
oc to 1.7ghz, it keeps rebooting. i am using this kernel with team tiamat rom
[Xoom Android Development] Isun:
Not all devices/configurations can maintain the 1.7GHz OC. Never select to set OC on boot the first time you try to go that high. I had success with 1.5GHz in the past. To end the constant reboot or Boot screen lock, try to hold both the power button and volume up for a while.
[Xoom Android Development] kin24173493:
thx for your advice.:)
[Xoom Android Development] zonk7ate9:
Will this Kernel work on a 4G Xoom running stock 3.2.2? Thanks.
[Xoom Android Development] okantomi:
I think so have had success and others not. Make a nandroid backup first and give it a try.

[Xoom Android Development] brandenk0:
Thanks for the awesome kernel! Everything is working fine. Just to ask what is the difference between the lagfree governor and interactive? Is there a major difference in battery life? I noticed that the lagfree governor is a lot more snappier transitioning between the OS. Again thanks for the awesome work.

Sent from my Galaxy S II using CM7
[Xoom Android Development] rockjock2020:
Downloaded when I saw your post on Twitter. Running smooth, so far no death sleep, or any 4g drop. I've run 1.5-1.7 so far all has been smooth. I've had no lock ups or random reboots. As you said took a bit for the first boot after that smooth sailing.

Miss the functions of the Rom being on 4g but this helps ease the pain. I can again use my USBOTG and have my Xoom back to the way Team Tiamat intended.
[Xoom Android Development] ghoticov:
Working great! I am sooooooo happy to have OC back! Thanks for all your hard work!
[Xoom Android Development] Isun:
This made my day. Thanks! I think lagfree is a bit more aggressive at upscaling than interactive but I'm not certain.
[Xoom Android Development] sakenfenc:

solarnz, does this work for wifi-only Xoom on 3.2 w/Moray Rom?

I've tried to flash it twice and just bootloop for 30+ minutes each time, I've restored fine but am wondering if this will require a wipe, or if it is for 4G only.
[Xoom Android Development] Elysian893:
I had to wipe, first time ever for a kernel, as far as I remember :/ had an old Titanium Backup so I didn't lose everything but did lose some... Did a nandroid after the first boot loop, gonna see if I can't get some of the stuff off of it.
[Xoom Android Development] okantomi:
So did it finally boot up for you? If so, how long was the 1st boot cycle I have a lot of installed apps but I'm on 12 minutes the third time around. I think I'll have to wipe.

It's cool.

Update: OK, finally did a wipe and it worked. Thanks!
[Xoom Android Development] davidsos:
Downloaded directly to my Xoom and installed like a charm. I'm glad that you mentioned the 8 minute first boot time, mine took a little longer and I would've started wondering.
[Xoom Android Development] solarnz:
Yes, I have a wifi xoom. And it works fine on my tablet (of course) :)
[Xoom Android Development] Elysian893:
I waited at least 15min before I finally wiped.
[Xoom Android Development] Isun:
It's seems like it works well with no signal drop. I reset a few times and noticed that it took about 7 minutes each time to boot. I thought it would just be the first time but it seems to keep taking about that long. Working great otherwise.
[Xoom Android Development] musashiken:
No problems flashing the stock GPU one on my Xoom Wifi. Coming from Team Rogue's Electra kernel. No wipe required.

Took me 10 mins to wait for it to boot up completely.

Works pretty fine, lagfree governor actually lags a wee bit for me, so I'm back to interactive.

Too bad the graphical glitches on boot splash screen are still there.

Edit: OS Monitor still shows the 2nd CPU core underclocked on first boot.

Edit2: Not only the first boot is long, the second boot and probably subsequent ones are long as well! Hmm.. I'm not so keen on this kernel now..
[Xoom Android Development] rockjock2020:
has anyone tried loading this with a vzw Xoom with moray w/ 4g? .... Biting the bullet did a back up lets see how well it does
[Xoom Android Development] bobbydiv:
Same for me on the booting up. It's taking about 5 minutes or so. I had an unexpected reboot when my system decided the 1.7 was a little too much power for it's on ability. Got it set at the 1.5 now, running smooth.

Still learning all of this, so the different governor etc....
[Xoom Android Development] kokjsch:
Ahh.....

long time no see team tiamat. :)

Thanks a lot and i will report the bugs.
[Xoom Android Development] solarnz:
The rom still doesn't support 4G... and won't be coming until ICS.
[Xoom Android Development] mutiny:
I got bootloop on both stock and OC GPU, solarnz. :/

EDIT: I guess it isn't bootloop, but a rather super long boot up. :]
[Xoom Android Development] iBuzman:
Thx!

Works well flashed over the top of XoomZone2.2.2

Thx again...

ps. Cf-Bench scores up vs Rogue Electra - both 1.5oc but now lagfree instead of interactive.
[Xoom Android Development] rschenck:
I just flashed Odachi with GPU overclocking over Moray (with Tachi GPU overclocking installed) on a Xoom WiFi.

The install went flawlessly for me with no bootloops. However, as has been stated the first bootup was LONG, which may be why some people are encountering (or think they are encountering) bootloops after installing the new kernel. My first suggestion in that situation would be to just power down the Xoom and try to boot it again.

As for performance, I find this kernel to be noticeably snappier then Tachi. I am not sure if this is due to the Nvidia fixes listed in the changelog, or using Lagfree scheduler. Either way, I am very pleased.

Team Tiamat keeps going from strength to strength and I can't wait to see what they do with ICS.
[Xoom Android Development] davidsos:
We have a problem. Boot times are much longer than the previous kernel, worse than booting MS Windows Vista on a system loaded up to the gills with services. What happened? I'm beginning to wonder if I should go back one version. First I'll see if this kernel has any noticeable advantages and what the feedback from the devs might reveal. In any case Tiamat has delivered a solution/ experience that blows away stock.

Edit: 5:23 total boot time. It took 52 seconds to get to the boot animation. There was nearly 20 seconds of black screen between the red Moto screen and the boot animation. The harmless visual glitch at the end of the red Moto screen its still there but I'm not concerned. The over 5 minutes boot time seems excessive.
[Xoom Android Development] joshndroid:
installed this kernel on both my xooms a wifi only and a verizon 3G, runs great awesome... my boot time was long anyway so this wasn't much more lol.. running the OCGPU and got a noticeably higher score in cf-bench in the java range and its snappy as.. cant wait for your ICS droppage you guys have this device down!
[Xoom Android Development] teo91:
I did the update, I waited 5 minutes and Xoom has started. everything works fine:D

pls solve the loooooooooooooooooooooooooong boot ime issue =)
[Xoom Android Development] joshndroid:
who cares how long it boots... it turns on.. haha
[Xoom Android Development] rschenck:
I agree...if you are rebooting your Xoom on a regular basis, you are holding it wrong.
